v0.4.6

Changelog

Features

• 技术债：把发布子系统（17 个函数 / 1018 行）从 runner.py 移入 release.py (Issue [#286]; PR [#696])
• 部署基准可配置：core 运行前不再无条件追 origin/main，支持 update_channel（分支 / 最新 release / 钉 tag/commit） (Issue [#534])
• Bug: check_release_gates 对刚 push 的 release 提交空 check-runs 判定 nothing to gate——CI 注册滞后窗口内带病提交过门（假成功） (Issue [#657]; PR [#670])

Reliability and recovery

• Bug: 双实例认领同一 Issue 的 TOCTOU——复查走搜索索引（最终一致）形同虚设，败者把在途交付打成 ai-blocked (Issue [#658]; PR [#668])

Deployment and operations

• ops 票需要完整执行能力（部署/写 GitHub/任意平台 CLI）：复用完整执行代理 + ops 剧本，废弃白名单沙箱方案 (Issue [#537]; PR [#703])
• P0：示例配置本身跑不起来——.orbi.example.toml 的两个 source_repos 被 runner 拒绝，而 cli 不校验导致 doctor 全绿 (Issue [#697]; PR [#700])

Bug fixes

• runner_health 崩溃计数把正常退出/预检失败计入，健康部署常驻 crash_loop 误报并派发幻影 ai-ready 任务；一次真实崩溃双行计数使阈值折半 (Issue [#617]; PR [#619])
• P0：429 重试计数随进程重启归零，limit=5 永不生效——交付无限循环、永不转 ai-fix-needed (Issue [#698]; PR [#701])

• CI failure: tests on branch fix/claim-race-yield (pull_request) (Issue [#704])

Correction (post-release): an earlier version of these notes listed Issue [#702] with PR [#705] under "Reliability and recovery". That entry was wrong: [#702] was closed as NOT_PLANNED (a duplicate of [#658]) and PR [#705] has never been merged. The concurrent-claim race is fixed in this release by #658 / PR [#668] only. Tracked as [#707].
